Pupils were never taught sex or relationship education, according to officials, and were 'immersed in orthodox Islamic doctrine' - which could leave them vulnerable to being groomed by extremists.

Anwar, 34, and Ahmed, 41, were 'generals' in the campaign to enforce Islamic discipline in the school, according to the Birmingham-based panel.

They were found to have implemented 'an undue amount of religious influence in pupils' education', and could now face being the first British teachers to be banned from the classroom permanently.

A total of 11 other staff at Park View and Oldknow Academy face charges of misconduct over the 'Trojan horse' affair, which allegedly saw teachers conspire to introduce hardline Islamic teaching to schools in the West Midlands.

Yesterday, a National College of Teaching and Leadership disciplinary panel chose to accept the evidence of a staff member that Anwar and Ahmed were central figure in Park View's religious indoctrination programme.

The panel said that pupils were 'fed a diet of Islam' which had in turn 'stifled their development as normal teenagers'.

It also found that the conduct of the two men tended to undermine tolerance and respect for the faith and belief of others.

Chairman Mark Tweedle said that the teachers were 'guilty of unacceptable professional misconduct' which 'may also bring the profession into disrepute'.

He said that the claims were 'in no way concerned with extremism', but added: 'Pupils raised in a predominantly Muslim community and immersed in orthodox Islamic doctrine at school are more likely to feel isolated and inadequately prepared for the world as they grow up.

'As such they are more likely to be vulnerable from the actions and inferences of others who may exploit any sense of alienation.'

Mr Tweedle said the panel had found that 'Park View was leading the way in the introduction of Islamic practice - perhaps more so than in other British state schools.'

Among the allegations found to have been proven were the claim that Ahmed and Anwar 'reformed the school curriculum to exclude proper teaching of sex and relationship education, use of contraception and safe sex'.

Mr Tweedle went on to say that 'pupils' development was being stifled and they were not being allowed to develop likes normal British teenagers'.

The panel concluded: 'This omission meant the relevant boys were not being fully informed as to how to keep themselves safe [from STDs] and meant they were not being prepared for life in modern Britain.'

Mr Tweedle said both teachers had also failed to afford pupils the chance to 'explore different cultures and form their own views'.

Ahmed organised religious assemblies where boys were segregated from girls, and encouraged prayer during the school day through posters, a call to prayer on the school's loudspeaker system, and direct reminders to teachers.

Separately, Anwar was also found to have breached proper recruitment procedures at Park View's sister school Nansen Primary, in hiring a personal acquaintance as deputy headmaster.

Park View was placed in special measures by Ofsted after the 'Trojan horse' allegations came to light, and it has since been renamed Rockwood Academy.

Ahmed and Anwar will be told what sanctions they will face at a later date.
